SOUTHFIELD, MI -- There had been much heartache for family and friends of McKenzie Cochran, the 25-year-old Southfield man killed during a struggle with Northland mall security guards, but few answers or policy changes since Cochran's death Jan. 28.

Southfield Police Chief Eric Hawkins plans to speak publicly at 10 a.m. Monday about the death but the department says the investigations is still pending.

Southfield detectives are awaiting autopsy results before sending their investigation to the Oakland County Prosecutor's Office for a warrant review.

"The investigation is still ongoing and we have not yet received the final autopsy report," Southfield Police Lt. Nick Loussia said in a statement Friday. "We anticipate that it will take several more weeks to complete our investigation."

Cochran died after being pepper-sprayed and held to the ground by as many as five security guards.

A witness's video of the altercation is posted on YouTube and shows portions of what happened after police say Cochran told an LA Diamonds jewelry store employee he wanted to kill someone. Police also said Cochran had been spotted loitering near the jewelry store on the day he died and the one prior.

As of last week, the guards had not been disciplined or transferred from the mall.
